In the environment of steep rate fall and capacity expansion, EBITDA for the company during the quarter declined

by 11.5% to Rs. 18,753 million compared to Rs. 21,199 million in Q4FY17, largely due to higher operating cost related

to Roaming and Access (as outgoing minutes increased) and Network expenses. The EBITDA margin for the quarter declined from 26.1% in Q4FY17 to 23% in Q1FY18, the company said while reporting its ‘subdued’ financial performance.
